What Is a Cooling Exhaust Fan?

Fans are equipment that, similar to pumps but unlike them, pressurize and transfer gas rather than liquid. Fans are the most important equipment used not only for the air intake and discharge functions required by industrial processes, but also for the ventilation of residential buildings, workplaces, and especially communal living spaces.
Industrial equipment operating at high levels generally produces excess heat. These systems may carry a risk of overheating if suitable cooling equipment is not used.
Overheated equipment can create a number of risks, including reduced equipment performance, premature component and lubricant degradation, general system failure, and ultimately the possibility of fire and other safety hazards for users and facility personnel. Industrial cooling exhaust fans are fans produced to eliminate these risks. They cool the hot air in your facility while enabling your equipment and personnel to operate more efficiently.

Where Are Cooling Exhaust Fans Used?

Warehouses, stockrooms, and storage facilities,
Garages and public buildings, agricultural buildings,

Considerations for Fan Selection

Four parameters must be considered when selecting a fan:

Required Air Flow Rate
Pressure Losses
Acceptable Noise Level
Electrical Power Connection Type

The air change rate required for the space to be ventilated depends on the intended use of the space, the number of people and items inside, and their activity levels. The table alongside shows the recommended air change coefficients for different types of spaces.

Environment	Air Change Coefficient
Auditoriums	6-8
Paint Ovens	25-50
Vault Rooms	3-6
Cinemas and Theaters	5-8
Commercial Kitchens	15-30
Foundries	8-15
Gymnasiums	4-6
Laundries	10-20
Indoor Swimming Pools	3-4
Restaurants	8-12
Conference Rooms	6-8
Waiting Rooms	4-6
Copy Rooms	10-15
Machine Rooms	10-40
Shops	4-8
Dry Cleaning	5-15
General Manufacturing Areas	4-8
Hospitals	8-12
Laboratories	8-15
Normal Activity (non-smoking)	29 m³/h
Normal Activity (smoking)	58 m³/h
Light Activity	45 m³/h
Heavy Activity (industrial workspaces)	60 m³/h

Per-person air volumes in living and working spaces based on activity level can help determine the required air flow rate.

Based on the information provided above, the required air flow rate is determined as follows.

Q [m³/h] = Air change rate (1 hour) * Room volume (m³)

Q [m³/h] = Number of persons × Air flow rate required per person

After determining the required air flow rate for the space, an appropriate duct design should be carried out (taking into account noise and air velocity criteria) and pressure losses should be calculated. Depending on the environment in which the fan will operate, the fan type (axial, radial, roof, smoke exhaust, etc.) should be decided upon, and the appropriate fan should be selected from the relevant fan curve based on the determined flow rate–static pressure pair. To briefly illustrate the above with an example: an office has 5 employees, a ceiling height of 2.6 m, and a floor area of 50 m²; therefore, it has a volume of 2.6 × 50 = 130 m³. The air change rate given for offices in the air change coefficient table is 4–8. Let us take an average of 5. This gives an air requirement of 130 × 5 = 650 m³/h. Assuming normal activity in the office, 5 persons × 29 m³ = 145 m³ of air is needed for the occupants, giving a total air requirement of 650 + 145 = 795 m³/h.

Fan selection is made according to this flow rate requirement.

After completing the flow rate calculations, the location where the fan will be installed must be determined. Where will the fan be mounted — on the ceiling, wall, chimney, or ventilation duct? Another consideration is the voltage of the electrical supply to the fan. Since we used an office as our example, let us continue from there. Fans in offices are generally mounted on the wall or window. If domestic electricity is to be used, a single-phase fan should be preferred. For use in an industrial setting, a fan operating on three-phase (380 V) power should be used.
